Bowser??? is a robotic impersonation of the real Bowser. In reality, it's only the Koopa Bros. inside a giant machine. Its only attacks are rolling over Mario or whacking Mario with its fist. Its defense is 1, so normal attacks do little to no damage. Instead, using Bombette's Bomb and Body Slam is recommended. When defeated, the robot blows up and a fight with the Koopa Bros. is initiated.
- When Bowser??? blows up, you can see a picture of Princess Peach hidden inside the shell.
